I'm not sure just what your problem is here. The best solution would be
to make your strings "\xe7" and not "\\xe7". The former contains the
real byte 0xe7, while the latter contains three bytes. When the former
is written to a file, you will get whatever letter 0xe7 represents
depending on what encoding you use.
If you have a reason to not do that (perhaps you are prompting for some
data and want escapes to be recgonized) then you could use something
a = sys.stdin.readline()
a = eval('"""'+a.replace('"""','"""+\'"""\'+"""')+'"""')
